Kate Hudson's A-List Halloween Bash

Trick or Treat? For Kate Hudson's annual costume party at her Pacific Palisades home, it was all treats and costumed celebrities.

The actress's abode was transformed with pumpkins, spider webs, witches and even severed heads hanging from the trees. In the backyard, "the pool was covered and made into a dance floor," says a guest.

Hudson, who was dressed as a sexy stewardess (Kurt Russell was coincidentally a captain) was quite the hostess. "She made sure everyone had a blast! People were dancing like crazy outside and hanging by the bar," a guest says.
